Having sexual intercourse during menstruation?
If your girlfriend's menstrual period started on June 15 and you had unprotected intercourse, the likelihood of pregnancy depends on her menstrual cycle.
If her cycle is regular, ovulation typically occurs around 14 days after the first day of her period, which would be around June 29.
Engaging in unprotected sex during her menstrual period generally has a lower chance of resulting in pregnancy, but it is still possible, especially if she has a shorter cycle or if sperm can survive in the reproductive tract until ovulation.
If you want to take a pregnancy test, it is recommended to wait at least one week after the expected date of her next period for the most accurate result.
If she has a regular cycle, this would be around July 13.
Having unprotected intercourse without ejaculation inside still carries a risk of pregnancy due to pre-ejaculate fluid, which may contain sperm.
Therefore, while the risk may be lower, it is not zero.

Hello, the questioner: There is a possibility of pregnancy even if ejaculation has not occurred, as pre-ejaculatory fluid may contain sperm.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

When it comes to understanding pregnancy risks during menstruation, it's essential to consider several factors, including the timing of the menstrual cycle, the nature of the sexual activity, and the effectiveness of contraceptive methods used.
Firstly, the menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation, which is when an egg is released from the ovary, usually occurs around 14 days before the next period starts. This means that during menstruation, which generally lasts from 3 to 7 days, the likelihood of becoming pregnant is lower, as ovulation has not yet occurred. However, sperm can live inside the female reproductive tract for up to five days. Therefore, if a woman has a shorter cycle (e.g., 21 days), and she has unprotected intercourse towards the end of her period, there is a possibility that sperm could still be viable when she ovulates.
In your specific case, if your girlfriend's period started on June 15 and you had unprotected intercourse during her menstruation, the chances of pregnancy are relatively low but not zero. If she has a regular cycle, ovulation is likely to occur about two weeks after the start of her period, which means that the days immediately following her period would be the most fertile. However, if she has a shorter cycle, the risk of pregnancy could increase.
Regarding when to take a pregnancy test, it is generally recommended to wait until at least the first day of the missed period for the most accurate results. This is because pregnancy tests work by detecting the hormone hCG (human chorionic gonadotropin), which is produced after a fertilized egg implants in the uterus. Testing too early could result in a false negative.
As for the question of whether having intercourse without a condom but without ejaculation inside poses a risk of pregnancy, it is important to note that pre-ejaculate fluid (pre-cum) can contain sperm. While the concentration is typically lower than in ejaculate, there is still a possibility of pregnancy if sperm is present. Therefore, even if you did not ejaculate inside, there is a risk of pregnancy.
In summary, while the likelihood of pregnancy during menstruation is lower, it is not impossible, especially if the menstrual cycle is shorter or if there is any sperm present from pre-ejaculate. If your girlfriend is concerned about the possibility of pregnancy, it would be wise for her to take a pregnancy test after the expected date of her next period. Additionally, if you are looking to avoid pregnancy in the future, consider discussing more reliable contraceptive methods with your partner to ensure better protection.
